Application filed March 1, 1887. Serial No. 22 ,302. (No model.)

To all whom it may concern:

Be it known that I, HORACE \VYMAN, of WVorcester, county of Worcester,and State of Massachusetts, have invented an Improvement in W'arp-Beams,of which the following description, in connection with the accompanyingdrawings, is a specification, like letters-on the drawings representinglike parts.

This invention has for its object to improve the construction ofwarp-beams and increase their strength and durability.

My invention consists, essentially, in a beam or spool composed of abarrel having flanged heads, which are retained in place by metal .15caps bolted to the barrel, a projecting portion of the cap engaging oroverlapping the hub of the flange to retain it in place, substantiallyas will be described.

Figure 1, in elevation and partial section, shows a warp beam or spoolembodying my invention, and Fig. 2 an end view of the beam or spool.

The barrel A has at its ends suitablejournals, a a, preferably made aspart of a metal rod extended through the barrel. The wooden barrel isreduced slightly to form a shoulder, as 2, against which may abut thehead B, composed of cast metal and havingan open hub, as b, and suitablestrengthening-flanges, as b.

The hollow huh 1) receives within it a cap-plate, 0 C, having flanges orprojections c c, which overlap or cooperate with the ends of the hub,the body of the cap-plate preferably fitting snugly between the innerside of the hub and the reduced portion a of the barrel A.

The cap-plates C are connected togetherand to the barrel by long boltsD, having each a head and threaded for the reception of a nut, as d, thecap also serving to confine the heads securely in place. The cap plateat the left of 0 Fig. l'may have its holes threaded to be engaged by thethreads 6, cut on the bolts, which would enable them to be used asscrews I claim The barrel, the heads having the hubs, and 5 thecap-plates having flanges or projections to engage the hubs, combinedwith bolts or screws to confine the caps in place, the latter holdingthe heads on the barrel, substantially as described.

In testimony whereof I have signed my name to this specification in thepresence of two sub; scribing witnesses.

HORACE \VYMAN.
